Frequently Asked Questions

Locker fitment starts with the axle, not the vehicle name alone. Check the axle family, front or rear position, axle-shaft spline count, and the gear-ratio range or carrier break for the housing. If the axle has been swapped or modified, identify what is actually installed before ordering; two vehicles of the same model can use different locker applications.

An automatic locker engages without a driver-operated switch, while a selectable locker lets you decide when the axle is fully locked. Automatic designs are simple to operate but can change on-road handling characteristics. Selectable lockers give the driver more control but may require electrical or air activation hardware. Choose the operating style that fits how the vehicle is driven and used.

Sometimes. Air-operated lockers typically need a compatible compressor, while electrically activated lockers need the correct wiring and switch setup. Some kits include part or all of that hardware and others do not. Check the exact kit contents before ordering so the locker is not installed without the air or electrical components it needs to operate.

A differential locker can couple the two axle shafts so both wheels on that axle turn together when maximum traction is needed. That helps prevent one wheel from spinning away the available torque in mud, rocks, loose terrain, or other low-traction situations. Automatic lockers manage engagement mechanically, while selectable lockers such as the Eaton ELocker or ARB Air Locker let the driver engage the lock when needed. A locker is different from a limited-slip differential, so choose the traction type that fits the vehicle and intended use.
